RESUMEN
Inflammatory bowel disease (IBD) continues to carry an increased risk of colon cancer and national protocols for endoscopic surveillance are in place. [...]we propose the patient factors to consider when withdrawal of surveillance may be contemplated. Alternative strategies, such as the qFIT and virtual colonoscopy (either via CT or capsule), have not been used in IBD surveillance. qFIT, which measures the concentration of degraded haemoglobin and is raised in ulcerative colitis (UC) patients with active inflammation,12 13 has not been validated as a marker of IBD-related dysplasia. A faecal calprotectin threshold of >250 [micro]g/g to indicate disease activity is based on consensus and published evidence. 31-33 A three-point colonoscopy indicates a 45-minute procedure. 1st DR, first degree relative;CRC, colorectal cancer;FH, family history;IBD, inflammatory bowel disease;PSC, primary sclerosing cholangitis;qFIT, quantitative Faecal Immunochemical Test for haemoglobin The Gastroenterology GIRFT report has recommended the use of stool biomarkers to aid in the prioritisation of colonoscopy procedures on waiting lists.
